| 2024-08-06 | What??? | | Extremely complex but the only working fingerprint spoofing extension out there now that the original Fingerprint Spoofing extension/add-on has been removed from Github because later reiterations are malware and developer has stopped supporting it more than 5 years ago. On Firefox, but not Chrome it ramps up CPU usage and RAM. |
| 2024-07-05 | RYX | | The fingerprint protection this offers is comprehensive and is the only one that I have encountered that protects against the "Creepjs" fingerprinter. I have tested it against multiple other sites like browserleaks and fingerprint/demo. HOWEVER, about half the internet does not work with this extension because CloudFlare blocks you with a message "This Browser Is Out of Date" which makes you turn off the extension. If you can fix that issue, I'll mark this to 5 stars. |
| 2024-05-10 | BaraShiro | | Had to disable as it allocates way to much memory, sometimes > 20Gb. Hopefully this will be fixed in a future update. |
| 2024-04-22 | Adrian F. | | I had to disable this after the upgrade to Firefox 125.0.1 because it caused very high CPU (100%) and RAM (20G+) usage for multiple hours, without end. I used about:memory to discover that this was the culprit. After I disabled JShelter, the CPU usage and RAM dropped. |
| 2024-02-19 | ti-ap | | A great tool that everyone should be using, even if it's not perfect. I recommend it to anyone that will listen. On rare occasions some sites will break because they're using a really aggressive captcha or spam detection platform. Lowering the settings on JShelter and refreshing fixes this. I also disagree that notifications should be shown by default, if at all. Every site is using fingerprinting of some sort nowadays, so you just get a notification every time you go to a site and the notifications become noise. |
